Again he took half of the shield-bearing guards and Agrianians, the guard of cavalry and the horse-bowmen, and marched forward to the confines of the Gadrosians and Oritians, where he was informed that the passage was narrow, and the Oritians were drawn up with the Gadrosians and were encamping in front of the pass, with the purpose of barring Alexander’s passage. They had indeed marshalled themselves there; but when it was reported that he was already approaching, most of them fled from the pass, deserting their guard. The chiefs of the Oritians, however, came to him, offering to surrender both themselves and their nation. He instructed these to collect the multitude of their people together and send them to their own abodes, since they were not about to suffer any harm. Over these people he placed Apollophanes as viceroy, and with him he left Leonnatus the confidential body-guard in Ora,[788] at the head of all the Agrianians, some of the bowmen and cavalry, and the rest of the Grecian mercenary infantry and cavalry. He instructed him to wait until the fleet had sailed round the land, to colonize the city, and to regulate the affairs of the Oritians so that they might pay the greater respect to the viceroy. He himself, with the main body of the army (for Hephaestion had arrived at the head of the men who had been left behind), advanced into the land of the Gadrosians by a route most of which was desert. Aristobulus says that in this desert many myrrh-trees grew, larger than the ordinary kind; and that the Phoenicians, who accompanied the army for trafficking, gathered the gum of myrrh, and loading the beasts of burden, carried it away.[789] For there was a great quantity of it, inasmuch as it exuded from large stems and had never before been gathered. He also says that this desert produces many odoriferous roots of nard,[790] which the Phoenicians likewise gathered; but much of it was trampled down by the army, and a sweet perfume was diffused far and wide over the land by the trampling; so great was the abundance of it. In the desert there were also other kinds of trees, one of which had foliage like that of the bay-tree, and grew in places washed by the waves of the sea. These trees were on ground which was left dry by the ebb-tide; but when the water advanced they looked as if they had grown in the sea. Of others the roots were always washed by the sea, because they grew in hollow places, from which the water could not retire; and yet the trees were not destroyed by the sea. Some of these trees in this region were even thirty cubits high. At that season they happened to be in bloom; and the flower was very much like the white violet,[791] but the perfume was far superior to that of the latter. There was also another thorny stalk growing out of the earth, the thorn on which was so strong that, piercing the clothes of some men just riding past, it pulled the horseman down from his horse rather than be itself torn off the stalk.
